Please tell me what is the shelf life of freshly prepared solutions

#2

Shelf life of the solutions have to be established by evaluating the concentration of the solution on daily basis.
In general this study has to be carried out for 5 to 7 weeks.
Ex:If solution-A, concentration retained up to 7 weeks, then the solution shelf life can be given as 6 weeks.

Thank you, then I will paraphrase my question.
The monograph states Ā«This suspension is freshly preparedĀ»
That is, what is the storage time of this suspension?
8 hours? 24 hours?

Freshly prepared means the prepared solution should be used as much as within short period (retain its efficiency). Each solution have its own shelf lifeā€¦
The storage time can be established by conducting solution stability validationā€¦
